If they really cared about it they would ban tobacco, this is nothing more than a money grab for something that has no basis in reality. There have been studies done, and on average smokers(and obese people) cost the health system less than non smokers. This is a US link based on a study done in the Netherlands, but I would imagine it would be the same world wide.
